This series introduces a new KVM selftest (mem_slot_test) that goal is to verify memory slots can be added up to the maximum allowed. An extra slot is attempted which should occur on error. The patch 01 is needed so that the VM fd can be accessed from the test code (for the ioctl call attempting to add an extra slot). I ran the test successfully on x86_64, aarch64, and s390x. This is why it is enabled to build on those arches. Finally, I hope it is useful test!
